Image Captions overlap posts

Hello, I posted a topic with a similar problem about a week ago, however now that I’ve read some posts and have come closer to a solution, I still have one minor layout problem left.

If you visit, https://www.buckmcgrane.com , you can see the captions on the post overlap into the following posts.

I’ve tried something like,

.wp-caption {

              clear:both;
}

However, it fails to stretch the post to fit in the comment.

Is anyone else having a similar problem?

Thank you!
